Rare-earth-free iron nitride (Fe16N2) nanocomposite magnet material
MAGesty series permanent magnet material composed of iron (Fe) and nitrogen (N) only — zero rare-earth content — synthesized as high-purity Fe16N2 powder suitable for bonded and compression-molded magnet production.
AI-assisted directory summary. Technical specifications, performance metrics, readiness and compliance labels are unverified unless individually supported and reviewed. Proposed partnership routes do not establish supplier consent, export eligibility, or willingness to sign an NDA. Confirm claims and test conditions with the linked sources and supplier before procurement or citation.
Problem solved
Eliminates supply-chain and price volatility risk from rare-earth elements (Nd, Dy, Tb) by creating a permanent magnet from iron and nitrogen, the most abundant elements, while targeting magnetic performance comparable to NdFeB magnets.
Application contexts
- Automotive wiper/auxiliary motors (demonstrated with Mitsuba)
- Drone propulsion motors
- Variable-flux motors for EV traction
- Industrial servo motors
- Home appliance motors
Technical principle
Fe16N2 (alpha-double-prime iron nitride) exhibits higher saturation magnetization than pure iron with large magnetic anisotropy. Future Materialz developed a mass-synthesis process for high-purity Fe16N2 nanopowder (98%+ purity, 10-200nm primary particle size). The powder can be combined with Sm2Fe17N3 to form nanocomposite magnets via compression molding or injection molding (Sankei Giken collaboration). The resulting magnet uses zero heavy rare earth and minimal light rare earth.
Typical use cases
- Rare-earth-free bonded magnets for auxiliary EV motors (wiper, window lift)
- Lightweight drone motors with reduced critical-material dependence
- Industrial servo motors with stable rare-earth-free supply chain
- Mid-speed range traction motors for urban EVs
